Can't get specific resolution on external monitor

[idata]

Hi,

I've got 2 laptops: Dell D410 (4:3, native 1024x768) and HP Compaq (16:10, native 1280x800) and I have an external monitor with 1280x768 resolution.

I can get 1280x768 on my monitor using Dell, no matter what i have set up on internal display. Problem is when i want plug in ext monitor to HP. No matter how i try i cant see 1280x768 resoultion. Of course i don't use clone or extend display, just single display, or internal or external, so there is no interference caused by internal display resoultion boundaries. As far as i know if i switch between displays, options shown in display properties are taken from display you actually use. I have to mention i have same graphics adapters on both laptops: Intel GMA 915. According to all above who cares what kind of display is in laptops because resoultions are taken from attached device, right?

So who can explain why i can't set up 1280x768 on HP laptop, using same graphics adapters, same drivers, etc?

Hello,

Please bear in mind that this product has reached its End of Interactive Support so Intel no longer provides interactive support for this product via telephone, chat or e-mail.

The graphics controller drivers will support just about any video modes (within reason) that the Monitor's EDID (Extended Display Identification Data) claims to support, as well as modes defined within the Video BIOS Table (VBT), plus a basic set of static modes (mostly for monitors with no EDID): 640x480, 800x600, 1024x768, 1280x1024, and 1600x1200.

We suggest installing the latest monitor drivers and making sure that all the operating system settings for possible video modes are enabled. Also update you system BIOS. Installing this will update your VBIOS as well and should facilitate interaction between the graphics controller hardware and the latest drivers. Also, make sure that you have the latest monitor drivers installed (*.inf drivers). After this is done, please reinstall the latest drivers for your graphics controller.

Finally, keep in mind that the resolutions that your system can support can be limited by your Original Equipment Manufacturer depending on what they customized for your system.
